vBe-Litilniown that I, ELBRIDGE ./R.HoLMns,

a Citizen I'of fthe United States, fresiding at Woreester, iin the Acounty of iWorcester `.and State rof .Massaehusettm have infvented 'a v`new and useful rlube Frame for :Axm'inster Looms, of wliiolitlie following is fa specification.

This vinvent'mn relates to :improvements in tube frames ttor :Axmin'ster :looms and fmore particularly .to .means for securing the supporting 'brackets Ito the fbody of fthe tube frame.

.Tube frames used yin .Xmifnster looms for ivieaving Wide rugs fare :usually constructed of a tubular bar into the'ends .of which 'extend :arms carried by the supporting 'brackets. These arms fare secured to the lbar 'by means of a number of .screws which .pass .tlrru the bar into the farms, but this `construction is mostly, zand also, it is foundlthat the several screws Work loose, necessitating loonstamt aoare and :attention to keep the support'- ing brackets tight-ly secured in place on the tube iframes. v

.The principal object of any invention is to overcome these :defects byprovidinfg fa :single quielrly :attached SorenY which serves to hofl'd the :parte lin place by drawing together coacting Wedge surfac'es lon the bar and bracket.

YFurther objects of the inventionrelate to *ons and arrangements of parte which 'will appear hereinafter and be pointed out iin the claims'.

In the accompanying drawings, wherein two :forms of the invention rare show-n,

Fig. l is a front yelevation of vone end of a tube iframe having my invention applied thereto, parts being removed to show vthe in'- vention more clearly.,

Fig, 2 is an end elevati-on of the structure shown in Fig. l,

Fig. B is 'a view lsimilar to Fig. l but showing the manner of assembling the bracket and associated parts, v

Fig. 4 is a horizontal section on line 4-#4 of Fig. 12,

Fig. 5 is av vertical section on `line 5-5 of Fig. l, and l Fig. 6 isa view similar to Fig. .l but show'- ing a modified form of the invention.

ln carrying out my invention I pro-vide the customary tubular bar or member l0 with yarn vtubes l1 'held thereto in any de- 1923. Serial No. 647,159.

l sired manner. AIf it '-is desired t'o stiifen the frame tapered vvooden strips '12 may be driven therein, these strips terminating a short distance from theend of the tubular member to aflord space for parts to be described. v l v In the form of the invention shown in Figs. 1 5 the end of the bar or tu'bula'rrn'ember l0 is tapered slightly as at 20by having the t'op and bottom yportions thereof bent toward each other as shown in Figs. land 3. formed `with the usual -spool bearing 22 and Ahas offset therefrom -"chain `engaging itongue 28 which engages the chain ('11ot'shown)fusually found on the type of Axminste'r loom employing tube frames. Spring 'hook 24 may -be provided fto cooperate Vwith :the tongue 23 in. supporting' the tube if-reime 'on the chain.

-Arnis 25 `ertend'ffrom =a :plate 25 which is Welded yor otherwise. fastened tothe 'bracket 21. rlllie arms have outer faces26 'which are inclinedV vsimilarly tothe inclined Vfffa'o'es of 'the tapered parte 20. The 'arms are bent on themselvesto provide inner faces 27 which are preferably at Ia. `greater inclination with respect to the axis I'of the tubular 'member than lthe inclination of vfades 26.

Arranged to cooperate With faces 27 .is a wedge or block 28 having faces l2@ in Contact with said faces 27 vand Sso 'disposed' to force the 'arms against the taperedparts 20 'of the tuloul'z-irl member when 'moved toward the 'end of the fram-e. To eftect this movement 'a 'screw f Y30 is passed through sprin'' '24, bracket 2l iand plate 25a and threat ed 4into 'the block or 'Wedge '28'. .lhe block is shown .as 'bent up from 'a single piece of material, :and having the ends thereof abut-tiirg the farms to give strength 't'o Vthe The spool l'supporting 'bracket 21 is block, but I do not wish to be limited to this particular Construction. l

A In assembling 'the parts, vthe block is moved along the screw and' 'the 'arms draw-n together until they 'Will enter the tubular member `as 'shown in'Fig.4 '3, fthe rounded ends `3l of the arms and the flexi-y bility of the 'material from 'which 'platef25y and the arms are formed' facilitating this movement. The bracket is then pushed Vin place 'and the 'screw tightened until the arms 25 are foreed yagainst the 'taperedpart of the tubular member, the bracket being. thus f held securely to the .tube frame. It will be 30, j a tubular yarn tube carrying member, a supnoted that the end of the tapered parts of the tubular memberengage the bracket at y points adjacent both arms and the bracket isv therefore limited in its inward motion. Also, it Will be noted t-hat the bent ends 3l of the arms 25y lie in contactwvith the arms 4 3 being similar to the arms 25 shown in the preferred forni-of the invention. The spool bea-ring l2 and bracket Ll0 are secured together as by Welding or in any other manner. In other respects both forms of the invention are similar.

:It Will be seen` that in both forms of the invention the Wedgey shaped blocki'` forces the arms against the tubular 'member to hold the rbracket firmly in place and that the Whole structure is held together by a single relatively large screw Which can be readily released'to remove a defective bracket.

I-Iaving described my invention it is apparent that changes andmodifications can be ymade therein by those skilled in the art f vWithout departing from the spirit and scope of the inventionas set forth. in the appended claims and I do not Wish to be otherwise limited to thev details disclosed herein, but What I claim is:

2. In a ytube vframe for Axminster looms, a tubular yarn tube carrying member, a supporting bracket' therefor, the tubularV member having faces inclined With respect to each other, portions of said bracket having inclined faces in contact with the said inclined faces of the member, and means toA hold the corresponding contactinginclined faces of the member and bracket together in locked relation to vprevent relative movement of the bracket With respect to the member. 3.

lll). 'A

9. In a tube lframe yfor Axminster looms, Y
